This study aims to propose guidelines for the joint use of partial least squares structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA) to combine symmetric and asymmetric perspectives in model evaluation, in the hospitality and tourism field.

This study discusses PLS-SEM as a symmetric approach and fsQCA as an asymmetric approach to analyze structural and configurational models. It presents guidelines to conduct an fsQCA based on latent construct scores drawn from PLS-SEM, to assess how configurations of exogenous constructs produce a specific outcome in an endogenous construct.

This research highlights the advantages of combining PLS-SEM and fsQCA to analyze the causal effects of antecedents (i.e., exogenous constructs) on outcomes (i.e., endogenous constructs). The construct scores extracted from the PLS-SEM analysis of a nomological network of constructs provide accurate input for performing fsQCA to identify the sufficient configurations required to predict the outcome(s). Complementing the assessment of the model’s explanatory and predictive power, the fsQCA generates more fine-grained insights into variable relationships, thereby offering the means to reach better managerial conclusions.

The application of PLS-SEM and fsQCA as separate prediction-oriented methods has increased notably in recent years. However, in the absence of clear guidelines, studies applied the methods inconsistently, giving researchers little direction on how to best apply PLS-SEM and fsQCA in tandem. To address this concern, this study provides guidelines for the joint use of PLS-SEM and fsQCA.

The purpose of this paper is to focus on user innovation strategies and their stability in the video game industry. The main research questions addressed are whether a significant portion of video game companies employ user innovation, and how these strategies are showing signs of success and evolve over time.

From various online data sources, information was extracted for 2,003 video game companies and 3,923 video games and analyzed using quantitative statistical approaches.

The analysed data show that a significant proportion of video game companies rely on user innovation-related strategies. If user innovation possibilities are provided, user ratings also tend to be higher. Over time, this strategy of enabling user innovation becomes more prevalent, but companies do also abandon such strategies or use them selectively. Especially, never employing them is associated with decreased company lifespan.

This is the first paper providing a large-scale insight into the evolution of user innovation strategies in an industry.

This paper provides managers and clinicians with an analysis of routine data collected by seven speech and language therapy services in the UK. Managers in seven districts in the UK of varying size and location were asked to provide information on referrals, waiting times and attendances during the six month period, and to give a breakdown of the types of intervention offered and type of clients seen. These data were aggregated and comparisons were made with existing data on speech and language therapy services. The results revealed considerable variations in prevalence, staffing ratios and client management practices. The implications for service planning are discussed.

The enabling technologies that emerged from information technology (IT) have had a considerable influence upon the development of marketing tools, and marketing has become digitalized by adopting these technologies over time. The purpose of this paper is to demonstrate the impacts of these enabling technologies on marketing tools in the past and present and to demonstrate their potential future. Furthermore, it provides guidance about the digital transformation occurring in marketing and the need to align of marketing and IT.

This study demonstrates the impact of enabling technologies on the subsequent marketing tools developed through a content analysis of information systems and marketing conference proceedings. It offers a fresh look at marketing's digital transformation over the last 40 years. Moreover, it initially applies the findings to a general digital transformation model from another field to verify its presence in marketing.

This paper identifies four eras within the digital marketing evolution and reveals insights into a potential fifth era. This chronological structure verifies the impact of IT on marketing tools and accordingly the digital transformation within marketing. IT has made digital marketing tools possible in all four digital transformation levers: automation, customer interaction, connectivity and data.

The sequencing of enabling technologies and subsequent marketing tools demonstrates the need to align marketing and IT to design new marketing tools that can be applied to customer interactions and be used to foster marketing control.

This study is the first to apply the digital transformation levers, namely, automation, customer interaction, connectivity and data, to the marketing discipline and contribute new insights by demonstrating the chronological development of digital transformation in marketing.

The lower density of powder metallurgical (PM) gears compared to solid steel gears leads to not only a lower weight but also a lower load-carrying capacity. Therefore, PM gears are cold rolled before hardening to increase the density in the highly stressed surface zone and, thus, the flank load-carrying capacity. A further approach to increase the flank load-carrying capacity is the reduction of friction and wear in the tooth contact. The purpose of this paper is to analyze the hard rolling process as a new manufacturing step in the PM process chain to influence the boundary layer.

The investigation includes the new process of hard rolling, the variation of the cooling lubricant in the hard rolling process and the evaluation of its influence on the material properties and the flank load-carrying capacity. Therefore, the additives of the cooling lubricant are varied regarding the sulfur and phosphorous content. The load-carrying capacity is evaluated on disk-on-disk test rig and the material properties are evaluated by metallographic tests and boundary layer.

The results of the specimen characteristics in the micro and nano range show a significant influence of hard rolling on the residual stresses and the chemical surface composition. Because of hard rolling, residual compressive stresses as well as roughness are reduced and the flank load-carrying capacity is increased by high phosphorous content of the cooling lubricant.

This paper investigates a new manufacturing step to increase resource efficiency by increasing the flank load-carrying capacity of spur gears.

The purpose of this study is to optimize high-strength gears produced by powder metallurgical process and to provide a material model to predict the tooth root bending fatigue strength. Powder metal (PM) technology offers great opportunities for the reduction of the carbon footprint and improvement of the cost efficiency of gear production. PM gears can achieve flank load-carrying capacities comparable to wrought steel gears if the loaded volume is fully densified. Still, the tooth root strength is of particular importance.

The tooth root stresses can be minimized by optimizing the tooth root geometry. This usually leads to a target conflict, as fully optimized tooth root geometries cannot be manufactured by generating processes such as hobbing, generating-grinding or rolling. To use the increase in tooth root load-carrying capacity of fully optimized root geometry on PM gears, a non-generating method for surface densifying is needed. The shot-peening process is used as an alternative densification process for PM gears. The properties of both shot peened and cold-rolled PM gears are analyzed and compared. To quantify the effect of both manufacturing processes, the tooth root bending fatigue strength will be evaluated and compared to wrought gears.

From the fatigue strength perspective, a material model is developed, which is able to predict local endurable stress amplitudes. The model is gained through regression varying carbon content, density and size effect on bending specimens.

It is transferable to PM gears of the same material using a load transfer coefficient.

This paper explores practices of foresight within the United Nations Educational, Scientific and Cultural Organization (UNESCO) program Futures Literacy, as a form of transnational governmentality–founded on the interests of “using the future” by “emancipating” the minds of humanity.

The paper draws on ethnographic material gathered over five years within the industry of futures consultancy, including UNESCO and its network of self-recognized futurists. The material consists of written sources, participant observation in on-site and digital events and workshops, and interviews.

Building on Foucault's (1991) concept of governmentality, which refers to the governing of governing and how subjects politically come into being, this paper critically examines the UNESCO Futures Literacy program by answering questions on ontology, deontology, technology and utopia. It shows how the underlying rationale of the Futures Literacy program departs from an ontological premise of anticipation as a fundamental capacity of biological life, constituting an ethical substance that can be worked on and self-controlled. This rationale speaks to the mandate of UNESCO, to foster peace in our minds, but also to the governing of governing at the individual level.

In the intersection between the growing literature on anticipation and research concerning governmentality the paper adds ethnographically based knowledge to the field of transnational governance. Earlier ethnographic studies of UNESCO have mostly focused upon its role for cultural heritage, or more broadly neoliberal forms of governing.

For better understanding the connections between the Viennese circles in which Menger was involved, it is necessary to make some remarks on the Viennese context where they developed. Since the end of the 19th century up to the interwar period, Vienna was a very lively city from a cultural point of view, the birthplace of modernism (Janik & Toulmin, 1973). In the age of the late Habsburg monarchy as well as in the post-First War ‘Red Vienna’, the intellectual, scientific and artistic life of the Austrian capital was so fervent that those years are recalled by historians as the Viennese Enlightenment, the gay apocalypse and the golden autumn: ‘two generations were enough to cover the whole period. The economist Carl Menger (1841–1920) shaped the beginning, and his son, the mathematician Karl Menger (1902–1985), witnessed the end’ (Golland & Sigmund, 2000, p. 34). After the First World War, from an economic point of view, a high inflation overwhelmed the country; while from a political point of view, ‘the new Austria was fragmented and labyrinthine’ (Leonard, 1998, p. 6): the Christian socialists were the conservative part of the society, but one third of citizens supported the new social-democratic party, which had the majority in Vienna.
